Answer:
B
Step-by-step explanation:
-(x^2+4x-21)
If you were to factor this, it would be,
-(x+7)(x-3)

Answer:
The answer is no solution.
Step-by-step explanation: First, you would add + 12 to both sides of the equation so that you would have 5c + 21 = 5c. Then, you would subtract 5c from both sides of the equation. This would leave you with 21 = 0. Since this is not true, the equation would have no solution.
Answer:
$70,750
Step-by-step explanation:
The expected gain/loss is found by <em>adding the products of all of the profits/losses by their probability</em>. So,
<em>(0.8 * 100000) + (0.1 * 0) + (0.1 * -2500)</em> =
<em>80000 + 0 + -250</em> =
$70750
The object's maximum height is the same as the y-coordinate of the vertex.To find that, first, finds the x- coordinate(t).You can find it by:
first identifying a,b and c.Multiply the b by negative 1 or simply change its sign and divide it by 2a.Afterward, plug the answer in the equation to find y, your answer.
(ax+bx²+c=-16t²+64t+80). Therefore, a=-6, b= 64 and c=80
-64/2(-16)=-64/-32=2
-16(2)²+64(2)+80=144 ft
So the maximum height of the object, when launched 64ft/sec from a platform that is 80 ft high, is 144 ft
Hope this helps(there are other methods)
